Changes From Pulp 2¶
Importers -> Remotes¶
CLI users may not have been aware of Importer objects because they were embedded into CLI commands with repositories. In Pulp 3, this object is now called remote. The scope of this object has been reduced to interactions with a single external source. They are no longer scoped to a repository.
Distributors -> Publishers¶
CLI users may not have been aware of Distributor objects because they were also embedded into CLI commands with repositories. In Pulp 3, this object is now called publisher. They are no longer scoped to repositories either. The responsibilities of distributors related to serving content have been moved to a new object, the distribution,
A new feature of Pulp 3 is that the content set of a repository is versioned. Each time the content set of a repository is changed, a new immutable repository version is created.
Direct Lifecycle Management¶
A new feature of Pulp 3 is that each time a repository (really, a repository version) is published, an immutable publication is created.
Publications are hosted by distributions, which contain configuration for how and where to serve a specific publication.
The combination of publications and distributions allows users to promote and rollback instantly. In a synchronous call, the user can update a distribution (eg. “Production”) to host any pre-created publication.
